> DemandForwardingBridge sends messages to the other broker and asynchronously waits for
ACKs keeping message bodies in heap. Amount of un-ACK-ed messages kept in heap is not limited.
If local producer is fast then whole heap will be consumed by messages waiting to be ACK-ed
by other broker.
> Possible option to fix the issue:
> Don't wait for ACK from other broker when forwarding the message if some threshold of
un-ACK-ed messages is reached.
